    The PCM is the ECU. It is located inside of the dashboard on the passenger side, mounted against the kickpanel.

    "Grab some"? If you mean your going to find some from a wrecker or something I believe that the PCM is VIN# specific.

    I think it's the EEPROM chip that is car specific.

    Im still a little confuse. Can you be a little more specific. Inside the dashboard, but against the kick board? Picture would be nice for a dummy like me.

    Underneath the passenger side of the dash, there's a black plastic panel. It's right underneath the glove box. Once that is off, look up and to the right, and you'll see a silver box. That's the PCM. There's one or two screws that holds that on. It's then tilted and contored to get it to come out. It can be a PITA the first time you do it, but get's easier. Just be careful of the wiring, as it can be damaged easily, so go slow.

    Caddydaddy, I thought that the PCM was vin specific. I could be wrong, but I could have sworn that it was. I know that the AC module is.

    It's not in the glove box. You need to remove the panel that is under the glove box to get to the PCM that is to the right of that panel.
